Analog Inputs
CF 7
Pressure or temperature analogue input functioning
0 = Temperature / pressure NTC – 4÷20 mA :
The condensing temperature is controlled with NTC probe while for
the evaporating pressures of the circuits 1 and 2 and the pressure
probe configured as auxiliary output 1 and 2 are controlled with
4÷20mA transducers.
1 = Pressure control with 4÷20 mA:
To control the evaporating and condensing pressures it is necessary
a 4÷20mA transducer.
2 = Temperature / pressure NTC – 0÷5Vdc:
The condensing temperature is controlled with NTC probe while for
the evaporating pressures of the circuits 1 and 2 and the pressure
probe configured as auxiliary output 1 and 2 are controlled with
0÷5Vdc transducers.
3 = Pressure control with 0÷5Vdc:
To control the evaporating and condensing pressures it is necessary
a ratiometric 0÷5Vdc transducer.
